Benefits of technology

[0009]An aspect of the present invention improves the production efficiency for rechargeable batteries by applying water-soluble ink directly to the surface of the circuit board during the manufacturing process. Another aspect of the present invention provides a method of efficiently improving detection of water contact in a rechargeable battery.

Problems solved by technology

However, labels for detecting water contact need to be separately, often manually attached to the battery packs, which reduces the efficiency of producing finished battery packs.

Abstract

A rechargeable battery, and more particularly, a rechargeable battery having a function of detecting water contact. The area for detecting water contact is formed on the rechargeable battery or its component parts by applying water-soluble ink on a surface thereof. It is straightforward to form such a rechargeable battery and to easily determine whether the rechargeable battery or its component parts have been in contact with water.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 2007-115310, filed Nov. 13, 2007 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Aspects of the present invention relate to a rechargeable battery, and more particularly, to a rechargeable battery having the function of detecting water contact.[0004]2. Description of the Related Art[0005]Portable electrical / electronic devices that are compact and light, such as cellular phones, notebook computers, camcorders and the like, have been developed and are currently produced. Battery packs are embedded in such portable electrical / electronic devices, so that the portable electrical / electronic devices can operate in places where a separate power source is not provided. For economy, battery packs generally use rechargeable batteries. Representative example...
